Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

Join us for a journey with electrons in this video! We explore the motion of an electron through a resistive strip powered by a 12V battery. Discover the electron's direction, work done by the electric field, and the transfer of energy to thermal energy in the strip.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.
